Argon-Oxygen Decarburisation (AOD) Refractories. More than 30 years ago most AOD Linings were constructed with Magnesia Chrome refractories. Over time the AOD linings were switched to Fired Dolomite and Fired Magnesia Enriched Dolomite. Today virtually all AOD Linings are now constructed with these refractories.
